Abstract
To suppress variations in the shift amount of the zero point of a sensor output when a pipe is connected to a pressure sensor via a clamp. A pressure sensor includes two semiconductor chips in two straight lines, orthogonal to each other, that pass through a center of a diaphragm in plan view, two resistors in the region between two supporting members supporting one semiconductor chip, and two other resistors in the region between two other supporting members supporting the other semiconductor chip.
